Update 5: It's official – PowerA has run out of free MOGA systems. In a post to Facebook on the matter, PowerA assures readers that "Santa still has something in his bag for you," so we may see another awesome deal soon.

Update 4: Well this has been a roller coaster – it seems the promo code is once again working.
Update 3: It looks like while PowerA is online, the site is no longer offering the MOGA controller deal.
